Le secteur financier est un composant essentiel de l’infrastructure critique et économique d’un pays. C’est aussi un secteur souvent ciblé par les cyberattaques, et ce, avec succès. Les pays développés mettent beaucoup de ressources pour prévenir et contrecarrer ces attaques, mais cela est moins le cas pour les pays en voie de développement, car ces …
Les outils technologiques à eux seuls ne peuvent garantir aux utilisateurs d’assurer leur sécurité lorsqu’ils naviguent sur Internet. Les comportements et les interactions sociales sont aussi importants que le matériel informatique ou les logiciels. Qu’est-ce qui détermine donc, dans notre comportement en ligne, les facteurs associés à l’utilisation d’un logiciel antivirus? C’est cette question que …
Rowhammer attacks are really interesting. They uses some of the physical properties of how computer memory is designed to overcome the logical control of how it is used. The bits of information are stored so close together in modern memory that if you ‘wiggle’ one bit fast enough, sometimes the ones next to it flip …
Luigi Logrippo at the Université du Québec en Outaouais presents the importance of multi-level access control methods for access control, data secrecy and data privacy. They suggest that an access control system that intends to provide secrecy and privacy must implement a multi-level access control method. In a system with data that is secret and …
At the upper end of security practices there is isolation. Disconnecting a computer from the network and of course the Internet provides a layer of physical control to system access. This air-gap is used to provide a barrier to information theft on individual computers and networks that contain very sensitive data by militaries and organisations. …

While there have been efforts to educate older children about the dangers of the internet and their privacy there has not been as much …
Probing the limits of anomaly detectors for automobiles with a cyber attack framework Adrian Taylor (Defence R&D Canada), Sylvain Leblanc (Royal Military College of Canada), and Nathalie Japkowicz (American University, USA) Modern vehicles are increasingly governed and controlled by a network of computers. Automobile security requires that these networks are secure. Detecting malicious traffic on …
Privacy, security and policies: A review of problems and solutions with semantic web technologies Sabrina Kirrane from The Vienna University of Economics, Serena Villata from Université Côte d’Azur, and Mathieu d’Acquin from the National University of Ireland Galway provide a look at how Semantic Web technologies research is progressing with relation to privacy and security concerns. They …
